(Eth r objects of the invention will inaf'ter forth.

In the accompanying drawin s, Figure 1 is a front view of the improvedstop device. Fig. is a top sectional View on line 2 2 of Fig. 5, showingthe construction of the stop device and the means for clamping it in theislet of a reeiproeateiy table. Fig. 3 is n front view showin theadjustable stop devices and port of J hleqeversing nieehan ism notedanon by said devices and. i a: is a sec ional view on line 4 d'oi Fig.12 oi a block 5 stop.

tien of which at the completion of the table travel in either directionis the work to be nrir-oinplished i..-hrougl1 the device undereonsiderntion. An arni 11, fast upon the shaft 32, is provided with awedge-shaped terminal 13, \vhieh. acted upon by the similarlyshapedplunger 10, backed up by a sprin (not shown) in the swinging lever 9,pivoted at 15.

At its upper extremity the arm 9 is nermally in the path of thestriking-points of the stops 8. Owing to the arrangement ofconstrnetirm, the position of the arm 9 inclines in the direetionopposite to that of the movement of the taole, this condition insurin acontact of the st1iking-point of stop 8 with the end of lever .9, andtons tlllOWil'l said. lever over through a small re of travel, the talle being then stopped in its movement and the stop device mnlaining onthe same side oi lever 9. Should it he desired at any time to givegreater movement of the table than that given by the setting ol theserew-stops 8, the plate or base 3 may he lifted out oi the path oi thelever; but on the return of the table the stop requires no attention, asit readily swings upward and rides over the lever.

Preferably the strildng-point or stop 8 is given the form of a serew, sothat sniall.adjustnieiits may be made after the clamping ol theapilianee in the "islet of the table; but this, wade useful, is notnecessarily em )loyed, for other devices may he substituted thereforwithin-it departure from the invention.

As above stated, should it be desired to obtain a longer stroke of thetable in either iiirmfltion the plate 3 is swung u )Oll the bushing 4out of the way and then allowed to drop to normal position with itsstop-shoulder 3" inengagnmont with. the pin 14. N ow on the table theswinging step-aria in readiness to accomplish the Work for which it isdesigned on the next movement of the table.

Chsnges may be made in the form and proportions of the various parts inthe improved stop device, and many of its details may be variouslymodified Without departure from the invention.

Having thus described the invention, whet l clsim is 1. A stop devicefor reve sing mechanism, comprising a support having a guidewey; sperforated block; e bushing inserted in the perforation of the block;and having it been ing' -surfnce exterior to the block; a bolt withinthe bushing, end having ahead fitted in said guidewey of the support; sstop 1nounted for swinging movement on said portion of the bushingexterior to the support; and means applied to the bolt for clamping thehead of said bolt in any ed'nsted position along the support, said meanscaring against the end of the bushing.

2. The combination, with a support having a guidewsy, of s perforetedblock overlapping said guidewey; a stepped bushing in serted in theperforetion of the block; it stop swinging upon said bushing exterior tothe block; e bolt inserted in the bushing, and having {1, head fittingssid'guidewey; and a nut threaded upon the bolt, and bearing against theend of the bushing.

8. The combination, with a reciprocstory support having: a guidewsy, ofe perforated block overlapping said guidcwsy'; e stepped bushinginserted in the bore of the block the bushing having it flen e at itsouter e lit-- ity; a bolt within the hushing, and havii'ig' heed fittedin the guidewsy 9, stop mounted for swinging movement noon the step ofthe bushing exterior to the block, end between. the end flange thereofand said block; and s nut threaded upon the bolt, nd serving to clampthe head thereof in the guidewey.

4. A stop device for reversing mechanism, comprising a erforeted block;or stepocd bushing flange at its outer end, insert-er in the. bore ofthe biocl-z, and projecting from said block; a plate swinging on thebushing, said piste having an arm; a bolt passing through the bushing; estop proper adjust in presence of two W tnesses.
